Application tiled April Il, 1901.

To if/ZZ whom t may concern:

Be it known that l, ROY DODSON, a citizen of the United States, residing at Dallas, inthe county of Dallas, in the State of Texas, have invented new and vuseful Improvements in I-lorse-Oollar-Blocking Machines,of which the following is Ya specification, reference' being had to the accompanying drawings and the letters of reference marked thereon, which form a part of this specification.'

My invention relates to machines for use in the manufacture of horse-collars, wherein the collars after being stuffed or filled are placed and by means of the combined action of binding and pressingare properly shaped, or, in other words, blocked; andthe objects of my improvements are to provide means whereby a horse-collar may. beheld during the process of blocking,which holder conforms to the nished outlines Vofthe collar; to further provide means whereby a' hinder may be brought firmly about the rim ,of the collar and there held while pressure is brought upon the body of the collar to properly shape it, and, further, to providemechanism whereby the degree of strain of theibinder about` the collar and degree of pressure upon it are independently under the control of the operator. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- I K n p Figure lis a side elevation ofthe machine; Fig. 2, a front elevation of the same; Fig. 3, a detailed plan of the head-block of the machine; Fig. 4,-a detailed plan of the drivepulley and adjacent parts of the machine; Fig. 5, a plan of the forming or blocking table of the machine; Fig. 6, a vertical crosssectional view of the blocking portion of the machine; Fig. 7, a detailed perspective of one of the openable nuts of the machine, and Fig. 8 a detailed side view of thecontrolling-lever of the machine. v

Referring to the said drawings, A is the bed-plate of the machine,supported on a frame and standards B and made with a forwardextending portion O, which has the shaftbearings O and C and fixed to the bottom of the plate the shaft-bearings D and D.

Fixed upon plate A is the collar-forming block E, made with the central upright por- Serial No. 55,390. (No modell) tion El, shaped to the inner form of a horseblock is further made with a two-part neck portion E", which extends between upright danges of part O, where it is secured, and ther-eat yforms a guideway, upon which a nuthead block is placed and arranged to slide, as will be vhereinafter described. Said part E terminates with a shaft-bearing F, and fixed across. the part E" adjacent block E is a box F', and journaled in said bearings is a shaft G, made screw-threaded throughoutits length between the said bearings, which screw portion thus arranged passes through a nut-head block H, which is placed to slide on said guideway, and through an openable nut H', which is housed within said head. Journaled in the bearings O and D D, respectively, are two sections of shafting I andI, the section I having fixed thereon a bevel-gearJ and a frictiondisk L, and section I a bevelgear K and .friction-disk L', and between 'said disks, sleeved on the adjoining end portions of said shafts, is a belt-pulley M, made 4with end iianges of like diameter as disks L L and vadapted to be brought to frictionally engage lsaid disks, and thus independently drive .either shaft-section.` One section of said pulley is made with a reduced Vneck having an' gannular groove M', wherein thefork of a' lever N engages to throw the pulley in either direction, and thus bring the pulley-flanges to frictionally contact the said shaft-disks. An upright shaft O is journaled in bearing C and has thereon aV gear J', in mesh with gear J, and a gear P, arranged in mesh with a corresponding gear P' of screw-shaft G, which shaft and gears connect said screwshaft G and shaft-section I, so that movement of shaft I will be imparted to screw-shaft Gr. Lever N is bracketed to frame B, as shown in Figs. 4 and 5, and is through the agency of rod N connected with the p machine-controlling lever Q, which is fulcrunied to plate A, as shown in Figs. 5 and S, and said lever Q. is provided with a hand latch-piece Q', which operates in conjunction with a segment Q" IOO sition between disks L and L'. rlhe nut-head block H has f ulcrumed thereto a lever R, which at its upper end is pivoted to a sliding plate R', arranged as a cover to block H, and which is made with eccentric slots, which register over upright pins H" of the two-part nut l-I' and by the action of the plate cause the parts of the nut to move from or toward each other by reason of said pins working in said plate-slots. Connecting the lower end of said lever R is a rod R", which through the medium of an intermediate lever S, which is bracketed to frame B, is connected with a push7 and pull rod S', which when actuated works plate R' and the parts of uut H' so said nut will engage and mesh screw Gor open from such engagement. The free end of said rod S' rests upon a grooved roll S", which permits free travel of the rod and terminates with a handpiece suitable for grasping by the hand.

Fixed upon opposite sides of bed-plate A are two upright hollow standards T, preferably gas-pipe, which bear at the upper end each a sheave-wheel T'. Sleeved on said uprights is a head-block U, which is, through the agency of a pair of attached cables, counterbalanced by means of a weight W. Pivotally fixed upon said head-block is a twopart openable nut V, having upright pins V', arranged operating in eccentric slots of a lever V", which is fulcrumed between said pins and actuated to open said nut parts from or close them in mesh upon a screwshaft X, which extends vertically in the central portion of the machine, being boxed in block E and bed A, having iixed thereon a bevel-gear K', in mesh with gear K, whereby motion is imparted from shaft-section I' to said screw, and block U is made with a vertical opening, through which said screw is arranged. In service nut V is opened and head-block raised by grasping and lifting on the side handpiece thereof kto a position as shown in Fig. 2. A collar is then placed on block E about the upright portion thereof, and a cable Z (shown in Fig. 5) is then placed about the rim of the collar, crossed at the top end of the collar, and the ends thereof placed on hooks Y, which are integral with and eX- tend sidewise from nut-head block H. After said cable is placed head-block U is brought down to rest upon the body of the collar, as shown in section, when its nut V is closed to mesh with screw X. At such stage of operation nut H' is also closed upon screw G. Lever Q is then grasped and unlatched from segment Q" and moved to throw pulley so one of its flanges will bear against disk L and by friction during the holding of the lever drive screw G, and thereby move nuthead block out, and hence draw on cable Z. When sufficient tension is given the cable to properly bind the collar, the lever Q is reversed, causing the opposite pulley-flange to likewise engage disk L', and thereby drive screw X, which will force head-block U down upon the collar, and thus press the collar.

Vhen sufficient pressure is thus applied, le-

ver Q is set in its normal position. Lever V and rod S' are then worked to open the nuts V and H, which releases the pressure of binding-cable Z and head-block U, when said head-block is again raised, the collar removed and a succeeding collar placed, and another like operation had.

Having thus described myinvention, what I claim as new and useful, and desire to secure by Letters Patent, is as follows:

In a horse-collar-blocking machine, the combination with the forming-block having a two-part neck portion and a central upright portion, the neck portion being mounted and secured between flanges to form a guideway, of a nut-head block sliding on said guideway, an openable or separable nut housed within said nut-head block, and a screw-threaded shaft mounted in suitable bearings and pass` ing through said head-block and through the openable or separable nut, and means for connecting the said head-block and separable nut, substantially as specified.
